Variation in the body growth parameters of the ghost crab Ocypode quadrata from morphodynamically distinct sandy beaches

open access: yesBrazilian Journal of Oceanography
Investigations of patterns of distribution of sandy beach macrofauna show that dissipative beaches tend to concentrate higher richness and biomass at the intertidal zone, as well as better fitness and larger sizes of a species, than reflective beaches ...

Atlantic ghost crabs (Ocypode quadrata) as coastal bioindicators: assessing human impact across the South Atlantic Bight

open access: yesFrontiers in Ecology and Evolution
Sandy beach ecosystems are increasingly threatened by human activity, making it critical to effectively evaluate their health. While this has often been done using an urbanization index (a tool that quantifies the level of human impact) and a ...

Spatial distribution of the ghost crabOcypode quadratain low‐energy tide‐dominated sandy beaches [PDF]

open access: yesJournal of Natural History, 2005
The spatial distribution of the ghost crab Ocypode quadrata (Crustacea, Brachyura) was described in five low‐energy tide‐dominated sandy beaches in Sao Sebastiao Channel (Grande, Zimbro, Pitangueiras, Cabelo Gordo, and Segredo). On each beach, the zonation study was performed on five random 1 m wide transects sampled from the water line to the ...

Moderate Dehydration Decreases Locomotor Performance of the Ghost Crab,Ocypode quadrata

open access: yesPhysiological Zoology, 1994
The effect of dehydration on the aerobic metabolism and endurance of sustained, terrestrial locomotion was determined for the ghost crab, Ocypode quadrata. The rate of evaporative water loss, measured as the percentage of decrease in body mass per hour, was influenced by ambient temperature $(T_{a})$.
